Toning, however, was the chemical coloring of the silver portions of the image, which changed the normally black areas of the frame into colored ones. Early directors similar to England’s Robert William Paul (1869–1943) and James Williamson (1855–1933) made extensive use of both techniques, which might proceed in reputation all through the nickelodeon period and past. First, there was the matter of exactly regulating the movie roll’s intermittent but consistent Technology news motion by way of the machine, such that each body would journey between the projection lamp and the open shutter for the same period and on the correct tempo for proper projection. German movie pioneer Oskar Messter (1866–1943) developed the Maltese-cross system—still used at present in most projectors—to guarantee common “stop-and-go” motion (Cook, p. 9). This gear, within the form of a Maltese cross, sits atop the sprocket wheel that pulls the film through the projector.
